High ultra-processed food intake could be linked to psoriasis
Observational study: A study in which the subject is observed to see if there is a relationship between two or more things (eg: the consumption of diet drinks and obesity). Observational studies cannot prove that one thing causes another, only that they are linked.
Survey: A study based solely on people’s responses to a series of questions.
People: This is a study based on research using people.
Eating a diet high in ultra-processed food could be linked to psoriasis, according to international researchers. The team looked at data from over 18,000 people, 1825 of whom had psoriasis, with 803 cases being active. They found a link between high ultra-processed food intake and active psoriasis status, even after taking into account age, BMI, alcohol intake, and other diseases such as diabetes, cardiovascular disease, inflammatory bowel disease, and inflammatory rheumatism. While the study relies on self-report information which limits the interpretation of the results, the team says further studies could look at whether high ultra-processed food intake precedes or is a consequence of psoriasis flare-ups.
